[PLUG] setting up a network

[Eric Cunningham <agent@drexel.edu>]

Hi folks,

I need some advice on how to set up and manage multiple services on our
network.  Currently we have a single DSL line with a single external IP
address.  A debian firewall [box1] running IPChains is forwarding http
requests to an internal debian host [box2] running apache.  Also on box2
is an *attempt* at a WINS server with Samba for all of the Window's
machines on our network. 

I would like to add a primary DNS server and an email server but I'm not
sure where to place them.  If at all possible, I'd like to use the two
existing machines as I really can't afford a third.  I could obtain an
additional external IP address and place all services on box2.  However,
I liked the idea of keeping services behind the firewall if at all
possible.  I'm after functionality and relative ease of setup rather
being too security minded though.  I do have a third machine to use if
it would significantly improve the setup.  It's currently a much needed
starcraft machine though.  ;-)

So what's the best way to do this?  This is my best guess but I'd like
to hear suggestions.

Box1:  Firewall; internal and external interface
Box2:  Apache, Samba/WINS, print server; internal interface
Box3:  Sendmail & Bind/DNS server; external interface.

Thanks for your input!
